  • ELECTRIC POWER TAKE-OFF SYSTEM
    Publication number: 20240075815
    Abstract: A refuse vehicle includes a chassis, an energy storage device supported by the chassis and configured to provide electrical power to a prime mover, wherein activation of the prime mover selectively drives the refuse vehicle, a body for storing refuse therein supported by the chassis, a first hydraulic pump configured to convert electrical power into hydraulic power, a second first hydraulic pump configured to convert electrical power into hydraulic power, and a motor coupled to at least one of the body or the chassis and configured to drive the first hydraulic pump and drive the second hydraulic pump.

  • Air purifier and a method for controlling an air purifier
    Patent number: 11318407
    Abstract: An air purifier (10) uses an air purifier filter unit (12) and a sensor (26) for sensing the matter to be filtered by the air purifier filter unit. By monitoring (18) the performance of the air purifier combined with information about the air purifier filter unit, it is possible to determine a volume of the space in which the air purifier (10) is deployed.

  • Automatic inspection system using barcode localization and method thereof
    Patent number: 6382510
    Abstract: An automatic inspection system using barcode locator and the method thereof which can inspect a colored surface of a three-dimensional object having a barcode. The automatic inspection systems comprises a light source; an image-retrieving device; and an operating and processing device. The image-retrieving device retrieves three-dimensional images of the inspected object from various viewing angles. The three-dimensional images are converted into two-dimensional images, which are then connected to produce a two-dimensional image representing the inspected object by the operating and processing device. The two-dimensional image representing the inspected object is adjusted through the barcode locator. Thereafter, the two-dimensional image is compared with a reference object image previously stored by the operating and processing device to find the defined pre-defects of the inspected object.
